PRESS RELEASE Stockholm, Sweden, April 18, 2005 World Champion Skater Scott Hamilton will speak in Elekta's booth on his treatment for a brain tumor using Gamma Knife® surgery

Neurosurgeons attending AANS in New Orleans April 16-21 will be able to hear an Olympic Gold Medalist speaking about the industry's Gold Standard for stereotactic radiosurgery, Leksell Gamma Knife® from Elekta.

Scott Hamilton, a four-time U.S. National Champion, four-time World Champion and Olympic Gold Medalist will be hosted by Elekta, and will speak to attendees about his battle with testicular cancer in 1997 and his more recent diagnosis of craniopharnigioma, a rare, non-cancerous pituitary brain tumor. He was treated with Gamma Knife® surgery at the Cleveland Clinic on December 13, 2004.

Hamilton is noted for his inspirational talks on his life and achievements, as well as his humanitarian work with cancer organizations.

"We are delighted that Scott Hamilton can join us at AANS and share his experiences as a patient with medical professionals who routinely administer life-saving treatments using Leksell Gamma Knife®," said Anthony De Carolis, President and CEO of Elekta, Inc. and head of the U.S. operations of the Elekta Group. "Hundreds of thousands of people have been treated with Gamma Knife® surgery, and he epitomizes the patient who can benefit from non-invasive stereotactic radiosurgery using Gamma Knife® surgery, which offers unmatched accuracy and precision."

Elekta will display its fourth generation Leksell Gamma Knife® at AANS, as well as the revolutionary Elekta Synergy® S, the ideal extracranial counterpart to Leksell Gamma Knife®. "Elekta is unique in providing both stereotactic radiosurgery and radiotherapy solutions to optimize treatments, outcomes, and efficiencies with dedicated, disease-specific solutions" explained Jim Rose, Vice President of North America Marketing. "Other vendors force physicians to compromise, using an 'all-in-one' radiotherapy solution that has been modified for use in treating the brain."

Gamma Knife® surgery, or stereotactic radiosurgery, is a single-session surgical procedure performed by a neurosurgeon / radiation oncologist team using ultra-precise focused radiation to destroy the target. "The clinical track record documented by over 300,000 patient treatments, 217 highly successful Gamma Knife® installations globally, and over 2,000 clinical publications make radiosurgery ideal for critical brain surgery," Rose said.
